Sudden change in impact factor 2008 to 2009
Posted 16 July 2010 - 07:25 PM
Can anyone explain why a sudden change in impact factor for a journal should occur between one year and the next?
The journal I am thinking about is Molecular Biology and Evolution, IF 2008: 7.28 -> IF 2009: 9.87 (!)
Can anyone verify this? Did they change the way they calculate it or something?

I think there is the IF list for 2009 somewhere on this site. For 2008, I also have 7.28
